No, really, ROBOCOPY, if I ask you to copy those (large) .zip files from [here] to [there] there is absolutely no need to recreate the (empty) directory structure of the rest of [here] as well. Because there’s tens of thousands of sub-sub-sub-folders down there
Plus a handful of .zip files that I never knew existed.
Happily
ROBOCOPY “[there]” “[there]” /S /MOVE
nukes them in a satisfactory, if time-munching, manner.
